S-AV28

The S-AV28 is a kind of RF power amplifier module. It is intended for VHF band ham FM RF power amplifier module and hand-held transceiver.

Then is about S-AV28 maximum ratings (Tc=25): (1)DC supply voltage, VDD: 17 V; (2)DC supply voltage, VGG: 6 V; (3)input power, Pi: 50 mW; (4)output power, PO: 12 W; (5)total current, IT: 3 A; (6)operating case temperature range, Tc(opr): -30 to 100; (7)storage temperature range, Tstg: -40 to 110.

The following is about S-AV28 electrical characteristics (Tc=25): (1)frequency range, frange: 144 MHz min and 148 MHz max; (2)output power, PO: 7 W min at Pi=20 mW, VDD=9.6 V, VBB=4 V, ZG=ZL=50; (3)total efficiency, T: 50% min at Pi=20 mW, VDD=9.6 V, VBB=4 V, ZG=ZL=50; (4)input VSWR, VSWRin: 2.5 max at Pi=20 mW, VDD=9.6 V, VBB=4 V, ZG=ZL=50; (5)harmonics, HRM: -15 dB max at Pi=20 mW, VDD=9.6 V, VBB=4 V, ZG=ZL=50; (6)load mismatch: no degradation when VDD=15 V, po=7 W, Pi=20 mW, VSWR load 20:1 all phase; (7)stability: all spurious output than 60 dB below desired signal when VDD=7.5 to 11.5 V,  VGG=0 to 4 V, Pi=20 mW, VSWR load 6:1 all phase; (7)power gain, Gp: 25.4 dB min at Pi=20 mW, VDD=9.6 V, VBB=4 V, ZG=ZL=50.
